Simply because it is irrelevant?

It's quite impressive that a single entity controls 30% of the entire network hashing power, but stats don't lie and as of late, the total support for B2X is 15%, far from their actual claim. They could push through with their plan. But the million dollar question is, would people actually believe it again after the 'cancellation' they've made before?

As long as consensus isn't reach (which I highly doubt again in this case), no fork will happen.
